We are using the ADL5519 in a 45 Ohm system.

**Based on the ADL5519 data sheet recommendation:**

**Use 52.3 Ohm termination resistors to produce a 50 Ohm input impedance**.

We are using 47 Ohm termination resistors to produce a 45 Ohm input impedance.

What R1 and R2 resistor values should be used to get the original 22mV/dB slope?

The output slope is independent from the input matching. No change to R1/R2 is needed.
